To aZZw/wm ii /nay concern: I

Be it known that l, OSCAR A. SMITH, a citizen of the United States, residing at Cleveland, in the county of Cuyahoga and State of Ohio, have invented certain new and useful Improvements in Hub-Nuts and Methods of Making the Same, of which the following is a specification.

This invention relates to nuts, and more particularly hub nuts adapted for use with steel disk automobile wheels, the object of the invention being to provide an improved nut of this character, and method of forming the same whereby the cost of producing such nut is materially decreased, and which at the same time will be simple in construction and efiective in use. 1

In the drawings accompanying and forming a part of this specification, Figure l is a longitudinal sectional view of one part of this improved nut; Fig. 2 is a sectional View of another part thereof; Fig. 3 is a side view of the. member shown in Fig. 2; Fig. 4c is a front view of the member shown in Fig. 2; Fig. 5 is an enlarged sectional view of the members shown in Figs. 1 and 2 assembled; and Fig. 6 is a sectional view of a portion of a steel disk automobile wheel illustrating the manner in which the steel disk and the hub members of the wheel are all secured together by this improved hub nut, one of which is shown in elevation and another in section.

Similar characters of reference indicate corresponding parts in the several figures of the drawings.

It has been the practice heretofore in making nuts of thiskind, to make the same from a solid round bar, but this mode of procedure requires a bar as large as the largest diameter of the nut and as the cupshaped portion thereof is of greater diameter than any other portion of the nut, it follows that when the nut is made from a solid bar a large portion of the material at each side of the cup-shaped portion of the nut most be cut away and is wasted, and this waste together with the fact that it requires considerable time to cut away such a large proportion of the material in order to reduce the various portions of the nut to the required size, makes the formation of the nut from a solid bar a very expensive mode of procedure. In fact, the making of a nut from a solid bar requires substantlally one-third more steel than is necessary 1n making my improved nut, and as .these nuts are made on an automatic multlple spindle screw machine, it has been found by actual test that the production of that machine is increased 100% by making the nut in the improved manner herein set forth, as compared with the old way of making the nut.

Moreover, by making the nut in the manner hereinafter described it enables the hexagon wrench-receiving portion to be milled at one-third less cost than was heretofore necessary-to do this work from a solid bar, and the cost of the present improved prodnot is not increased by reason rung or stamping of the cup-shaped portion of the nut to the body thereof, owing to the fact that this just about offsets the cost of burring, which was heretofore necessary after the nut made from the solid bar had gone through the hexagon milling operation, so that it has been found in practlce by actual test that the present improved nut can be produced from to cheaper than it was heretofore possible when the nut was made from a solid bar.

In making this improved nut, it is only necessary to use a hexagon bar of substantially the size of the wrench-receiving or hexagon portion of the nut, since it is not necessary to cut away the bar to form this hexagon portion as has heretofore been necessary when the nut has been made from a solid bar. The nut 2 is suitably shaped as at 3 to form an ornamental end and suitably bored as at 4, and interiorly threaded as at 5, it having on its exterior a wrenchreceiving or hexagon portion 6 and is shaped to have a reduced portion 7. The

threaded bore is intended for the reception of the connecting stud 8, which in the present instance is shown threaded at both ends of the spin as 9 and 10, the threaded end 9 projecting into the threaded bore of one hub member 11 of the wheel while the opposite threaded end 10 of the stud extends into the threaded bore 5 of the hub nut. The tubular or sleeve portion 7 of the nut extends into an opening or bore 12 of the other hub member 13 while the stud 8 passes through the steel disk14: of the wheel and by drawing up the hub nut the steel disk is clamped between the two hub members 11 and 13 in a manner which will be readily understood. Located on the hub nut is a cup-shaped mem- ,ber 15 for the reception of a split washer.

The present improvement has therefore to do with the manufacture of this improved hub nut in an economical manner from a hexagon bar of stock materially smaller in size than has heretofore been necessary, and to do this the nut is formed'as a two-part member, but the parts are so connected together that to all intents and purposes they are an integral structureand in making this improved nut the body portion 2 hereinbefore described is provided with a step or shoulder 16, which in the present instance is formed by providing the body with a steppedportion as it were, stepping up from the tubular portion 7 or stepping down from the wrench-receiving portion 6 whereby a wall is formed against which the cup-shaped flange hereinafter described will be clamped.

The body portion 2 forms one member of the -two-part nut. The cup-shaped portion 2' constitutes the other member of the nut and is formed separately from the body portion 2, and can either be made from a round bar or pressed sheet steel in the manner shown.. This cup-shaped portion comprises a flange.

17 having an lnwardly extending flange 18 provided with an opening or bore 19 of a size adapted to fit over the shoulder 16 of the body 2 ofthe nut, and this inwardly extending flange 18 is provided with one or more (shown herein as three in number) notches or recesses 18' forming what I have termed as anchoring stations to assist in anchoring the cup member, and thus secure it to the body 2 of the nut, and prevent circular movement of one part relatively to the other.

After the cup member 2' is assembled on the body 2 of the nut in the manner shown in Fig. 5, the forward edge of the shoulder which has somewhat greater length than the width of the flange 18 of the cup member, is forced by pressing or peening or stamping orspinmng it over the forward face of the flange 18 as at 20, Fig. 5, which not only prevents the separation of the two members longitudinally of the body but also clamps the flange 18 against the wall 21 of the body, which is one of the results of the stepped formation of the body of the nut and at the same time a portion of this pressed metal 20 will enter the notches .or recesses l8 and thus prevent. the circumferential turning of the cup relatively to the body.

or vice versa, thus'eflt'ectively anchoring the cup to the body in a very efficient and rigid manner.

It follows by this mode of procedure in manufacturing this improved hub nut, that it is not necessary as heretofore, when the entire nut is made from a $0116. bar of stock,

ter of the. hexagonal portion and then shape it automatlcal to form the body shown in Fig. 1. onsequently a great saving in time in producing the nut is.ob tained and agreat waste of material avoided since it will be obvious that when the whole nut is formed from a solid bar that as the cup-shaped portion is materially larger in diameter than any other portion of the nut, it follows that in order to properly shape the nut a large portion of the nut at both sides of the cup-shaped member had to be cut away and as this material had to be cut away in the form of chips, it follows that it was simply waste material aside from the time and labor required to cut away all of this waste material, which made the production of the nut as hereinbefore stated, a very expensive one in that it required the use of large stock of the size of the extreme diameter or cup-portion of the nut, whereas by means of the present improvement, the nut body can'be made by using stock very much smaller in diameter than the extreme diameter of the cup-shaped member while the cup-shaped member canlbe pressed from steel so that there is'very much less waste in forming the nut in this improved manner than was heretofore the case.

In short, instead of using a solid bar of the extreme diameter of the cup-shaped portion of the'nut and then cutting it down to less diameter at one side of the cup to form the hex portion and at the other slde of the cup to form the tubular portion of the nut, as heretofore, this improvement permits the use of a hex bar of substantially the diameter of the hexagonal or wrench-receiving portion, so that no substantial part of the hexagonal part of the bar has to be cut away because the hexagonal stock or bar is supplied to the manufacturer in this form, and at the opposite side of the cup-shaped portion very much less material has .likewise to be cut away in order to form the tubular portion 7. Furthermore, this tubular portion 7 can be more readily formed as can also be the cupilliaged portion before these parts are assem- It will be understood that the various details may be more or less changed without departing from thespirit or scope of the present invention, as for instance, it is not material as to the particular manner in which the shoulder 20 is forced into engagement with the flange 18 of the cup member, as any suitable and practical way may be y L-A two-part a body member and a flang e member assembled and interlocked therewith by forcing a portion of the metal of the body memberlbeyond the normal face thereof into the edge and also against the face of the flange member, thereby to prevent movement of the same in a plurality of directions.
